I have read a lot of Frans de Waal's books. He would disagree. Chimpanzees respect ownership and will not take away food from low ranking members if they got their hands on it first.

They respect "possession", as long as the other ape has direct control. The new finding, by Tomasello, the most acclaimed researcher in great ape cognition and behavior, builts on this and shows they don't respect ownership. I wouldn't take that lightly.

Is the presence or lack of scent marking in primates considered?

Ownership is an abstract concept. Apes don't understand concepts.

I wonder what happens if they were able to teach to use tokens. The study structure looks like a prisoner's dilemma. I can't find out how the apes were raised. It sounds like they used children from local daycare, so that might affect norms + expectation of future retaliation.pic.twitter.com/7bAcCFzpfI

Makes me wonder if anyone is doing stuff like that with wild apes in a similar manner to the Wytham Woods Great Tits studies.
